CURTAIN AND OPERATING MEANS THEBEIOK,

Application filed November. 30, 1927. Serial No. 236,277..

This invention relates to curtains and, a room could be temporarily shut off from more. particularly to a set of curtains adapted to: be. mounted at opposite sides. of a window and moved across the Window toward each other into closing relation to the window. l

One. object o-fthe invention is to. provide curtains. having, their rollers rotatably mounted at opposite. sides. of a window and improved means to. rotate the rollers and move the. curtainstoward and. away from each other and prevent. the. curtains. from. moving out. of a set position. I

Another object of. the invention is to cause the curtains to he simultaneously operated in. proper timed relation to each other and cause the rollers to be rotated atsuch. speed thatthe. curtains may be freely unwound when moved into closing relation to a window and evenly wound upon their rollers when moved away from cachet-her.

Another object of thewinvention is. to permit. both of the curtains to be simultaneously adjusted by rotating a shaft whichmay be referred to asan operating shaft and has operative connection with both of the curtainsr p v p Another object; of the invention is to provide bracketsof an improved construction by means of which the rollers. may be rotatably mounted and retained in a vertical positionv hut permitted to be easily removed whennecessary;

The invention is illustrated in the accompany-ing drawing, wherein Figure l isa view in elevation showing. the improved curtains applied toa window;

Fig.2 is a fragmentary top plan view of the improved curtain structure Fig. 3 is afragmentary view partiall in elevation and partially in section and ilustrating the manner of rotatably mounting the upper-end of one curtain roller;

Fig.4: is a transverse sectional view on the line4-4- of Fig. 1, and Fig. .5: is a sectional view taken on the line. 55 of Fig. 4. v

The improved curtains and operating means therefor constituting the: subjectm-atter of this invention. has. been illustrated taken in operative relation to a window including a partition'by means of which a portion of the remainder ofthe roomi The two curtains which are indicated by the numerals 3 and 4 are of a duplicate construction and each includes. a. roller 5. The rollersextend vertically at opposite sides. of

thewindow frame and have pintles. or shafts.

of sheet metal and each inc udes an attaching;

flange 8 adapted to be firmly secured against the window frame and an arm 9 which projects outwardly from the window frame and is formed with a recess or pocket I0 leading from. one side. The. shafts or pintles. of the rollers are rotatably received in the pockets 10 of the brackets and each is retained in thepocket in which. it is received by a. latch strip H which is pivoted to the: arm 9, as shown at 12,, and has its other end portion. formed with a tooth 13 adapted to be snapped intoa socket 14 formed in the bracket.. Therefore, the rollers will be rotatably mounted and prevented from movin out of proper engagement with their bracl' rets but when it is. desired to substitute new curtains for those already in. use the latches may be. easily released in order tospermit the rollers to be removed from the. brackets and the. new ones set in place. i

I Rods 15 which extend vertically along the" free ends of the curtains are connected with the curtains by clips 16,. and these rods have their end portions pro'ecting above and below the curtains, as slown in Fig. 1.. In.- ternally threaded sleeves 1'? are. carried b the rods. in crossed relation to either e11 and these sleeves have threaded enga ement with shafts 18 and 19 which extend horizontally across the. upper and lower portions of the window frame adjacent the upper and lower ends of the rollers. Each of the shafts has right and, left hand threads leading from its ends and the sleeves. are threaded in ac.- cordance with the threading of the portions of the shafts upon: which they are mounted. It will thus be seen that, when the shafts are rotated, the sleeves carried by the rod 150i the curtain 3 will be moved along the shafts. in a direction opposite to the movement of the sleeves carriedby the rod of the curtain 4:. Therefore, the curtains will he moved toward or away from each other ac-- cording to the direction in which the shafts are rotated. Bearing brackets'l S are provided to rotatably mount the shafts l9 and 20 and the end portions of the shafts project from the brackets and carry beveled gears 21 which mesh with cooperatingbeveled gears 22 secured upon the ends of the pintles 6. By this arrangement the shafts and curtain rollers will be simultaneously rotated when rotary motion is imparted to the shaft 20 through the medium ofits crank 23 and the curtains will be moved toward or away from each other according to the direction in which the shafts are rotated.

VVh'en the improved curtains are in use,

they are applied to a window frame, as

shown in Fig. 1, with the curtain rollers disposed vertically at opposite sides of the window frame and the shafts 19 and 20 ex tending across the upper and lower portions of the window. When the crank" 23 'is turned to rotate the shaft 20, which may be referred'to as a drive shaft, the gears 21 carried thereby will impart rotary motion to the curtain rollers through the medium of the gears 22 at the lower ends thereof and the gears at the upper ends of the curtain rollers will transmit rotary motion to the uppershaft 19 through the medium of the gears at its ends. Therefore, the two rollers and the shafts will be rotated at the same rate of speed. As the shafts rotate, the sleeves 17 will be moved longitudinally upon the shafts at the same rate of speed and in such timed relation to rotation of the rollers thatthe curtains will be retained under slight tension and, therefore, held smooth and caused to be rolled smoothly upon the rollers when moved away from "each other and prevented from. wrinkling when moved toward each other into covering relation to the window." By this arrangement the curtains may be easily moved into and out of covering relation to the win- "jdows and prevented from having movement if the window is open. This will prevent the curtains from being damaged by wind blowing them. While I have shown the shaft 20 rotated by means of a .crank, it will be understood that any means desired may be substituted for the crank.

Having thus described the invention, 1 claim:

1. In a structure .of the character described, -vertically disposed rollers, means to rotatably mount the rollers at. opposite sides of a passage, curtains'wound upon said rollers and when unwound therefrom having movement towards each other across the opening, rods connected with the free ends of the curtains and projecting above and below the same, internally threaded sleeves carried by said rods, shafts each having oppositely threaded portions, means to rot-at ably support said shafts above and below said rollers, said sleeves being threaded upon adjacent shafts, means to impart rotary motion to one shaft, and interengaging gears carried by the shafts and rollers whereby when the last-mentioned shaft is rotated the rollers will be simultaneously rotated and the curtains moved into and out of closing 'relation to the passage.
